    (54) Processor modem


    (57) An improved data terminal equipment (DTE)-modem arrangement is disclosed. In this arrangement, a single processor, such as one that resides within a DTE, both executes an application program and implements a modem. A DTE that utilizes this arrangement, therefore, needs only a single processor to perform both the application and modem functions.
